What is Ably?
Ably clears its iOS SDK of a 'tracking' privacy label while pitching realtime to AI agents.
Ably is a realtime messaging platform that is repositioning its pub/sub infrastructure as transport for AI agent output, alongside LiveObjects shared state. Recent releases are SDK hardening: faster liveness detection, LiveObjects reaching stable across platforms, simpler channel rules and permissions, and now a corrected iOS privacy manifest.
What is Redocly?
Redocly's reunite.agent gets per-duty cron schedules, rules and source repos.
Redocly shipped three Reunite releases and a config release on Oct 28. The feedback and discovery duties in reunite.agent can now each run on their own UTC cron trigger, follow their own rules and read only listed source repositories. SCIM provisioning now accepts identity-provider groups of any size, where pushes over 1,000 members used to fail. @redocly/config 0.69.0 also adds per-rule impact settings for the experimental diff command.

Ably
5.0INFRA · APIS
Ably clears its iOS SDK of a 'tracking' privacy label while pitching realtime to AI agents.
◆ Current state
Ably is a realtime messaging platform that is repositioning its pub/sub infrastructure as transport for AI agent output, alongside LiveObjects shared state. Recent releases are SDK hardening: faster liveness detection, LiveObjects reaching stable across platforms, simpler channel rules and permissions, and now a corrected iOS privacy manifest.
◆ Where it's heading
The product is running two tracks: AI Transport for streaming and steering agent output, and steady maturation of the core SDKs and the config-as-code surface. The core work removes friction for app developers, such as App Store privacy labels, Terraform and permission rules, so the platform is easier to adopt.
◆ Prediction
Expect AI Transport to move toward a 1.0 SDK, and LiveObjects stable releases for the remaining platform SDKs.
Redocly
6.3INFRA · APIS
Redocly's reunite.agent gets per-duty cron schedules, rules and source repos.
◆ Current state
Redocly shipped three Reunite releases and a config release on Oct 28. The feedback and discovery duties in reunite.agent can now each run on their own UTC cron trigger, follow their own rules and read only listed source repositories. SCIM provisioning now accepts identity-provider groups of any size, where pushes over 1,000 members used to fail. @redocly/config 0.69.0 also adds per-rule impact settings for the experimental diff command.
◆ Where it's heading
Two threads run together: an agent inside Reunite that does recurring docs work (feedback and discovery) and is gaining scheduling and scoping controls, and enterprise plumbing such as SCIM scale, Git token rotation and permission fixes. Last week's configurable docs MCP server points the same way, with Redocly adding AI surfaces and making them configurable in redocly.yaml.
◆ Prediction
Expect more reunite.agent duty types or options in @redocly/config, and the experimental diff command moving toward a documented API-change check.
